smack_inode_getlsmprop(9)

πŸ“¦ version 7.3.1, in nixpkgs unstable

πŸ’– NAME πŸ’–

smack_inode_getlsmprop β€” extract inode's security id

okay so picture this: you're in the Kernel API Manual (yes that's the whole vibe, welcome 🫢) and you need the security id out of an inode. That's literally the entire job of this function. No cap, it just goes in and pulls the security id out. Iconic, lowkey, does one thing and does it well ✨


🌸 SYNOPSIS 🌸

void smack_inode_getlsmprop (struct inode *inode , struct lsm_prop *prop
);

bestie it returns nothing β€” void, as in, don't go looking for a return value, it's not coming 😭 it does its thing in place and that's that πŸ’…


πŸŽ€ ARGUMENTS πŸŽ€

  • inode β€” the inode you wanna extract the info from, like, the whole reason we're here πŸ¦‹
  • prop β€” the spot where the result gets saved. so it's a "you hand me the bucket, I fill the bucket" situation, fr fr πŸ“

πŸ¦‹ SEE ALSO πŸ¦‹

so there's a Kernel file at ./security/smack/smack_lsm.c and it's giving main character energy, because that file brings a whole entourage of friends. here's the entire squad, in order, no one left behind, I promise πŸ™ˆβœ¨
